5/40 = 1/8 so your taking it and dividing by 5
Area and perimeter are in the ratio of 1:3. but if u mean to ask about the ratio of perimeters & areas of both triangles. the answer would be 1:1
First we have the work out the area of 1 room. So that is 8ft * 12ft which is 96ft^2. And if there are 2 of these rooms, then we multiply this value by 2. Giving us a total area of 192ft^2.
So far, you've only defined f(x). You haven't asked a question.
2x+4y=8
-2x -2x
4y=-2x+8
/4 /4 /4
y=-1/2x+2
